    FCC gasoline, as a main blending component of automobile gasoline in China with a blending ratio of 70%,is the bottleneck that prevents further improving the quality of automobile gasoline. FCC light gasoline etherifying technology changes tertiary carbon alkene into ether,and makes up for the shortage of MTBE output.It not only raises octane rating and oxygen content but also lowers alkene content of gasoline and vapor pressure,thus is worth developing and popularizing.

    我国FCC汽油作为车用汽油的主要调合组分,其比例已占70%以上,是车用汽油质量不能进一步提高的瓶颈所在.FCC轻汽油醚化工艺将其中的叔碳烯烃转化为醚,在一定程度上弥补了MTBE产量的不足,除提高辛烷值和增加含氧量外,还可降低汽油的烯烃含量和蒸气压,一举多得,值得开发、推广。

    The State Center of Quality Supervision & Testing of Petroleum Products conducted a spot check on domestic gasoline quality in the first quarter of 1999.

    The State Center of Quality Supervision & Testing of Petroleum Products conducted a spot check on domestic gasoline quality in the first quarter of 1999. The spot check included 20 batches products from 20 enterprises, in which 90 unleaded gasoline and 93# unleaded gasoline were 15 batches and 5 batches respectively. According to the present domestic specification, the qualified rate was 100%. Although the overall qualities were stable and enhanced, however, the olefin contents were much higher than abroad; aromatics contents were low and benzene contents in most of the products were low. Aiming at the future product quality of gasoline production, some suggestions are presented.

    1999 年第一季度,国家石油产品质量监督检验中心对我国车用汽油产品的质量进行了抽查,共抽检20 家企业生产的车用汽油产品20 批次,其中90 号无铅车用汽油15批次、93 号无铅车用汽油5批次,按现行汽油规格,抽样合格率为100% 。虽然车用汽油产品整体质量稳定且有提高,但对某些即将控制的有害物质的测定结果表明,烯烃含量高,特别是90 号汽油的烯烃含量远远高于国外;芳烃含量目前尚可,但随着汽油牌号提高,芳烃含量将明显升高;苯含量虽然普遍较低,但个别样品苯含量太高。针对汽油生产行业在产品质量、生产与流通领域将面临的形势提出了一些建议。
